The Fourth International (FI) is a revolutionary socialist international organization consisting of followers of Leon Trotsky, also known as Trotskyists, whose declared goal is the overthrowing of global capitalism and the establishment of world socialism via international revolution. The Fourth International was established in France in 1938, as Trotsky and his supporters, having been expelled from the Soviet Union, considered the Communist International as effectively puppets of Stalinism and thus incapable of leading the international working class to political power. Thus, Trotskyists founded their own competing Fourth International.
